Um, wow, 3 showers a day. No wonder. FWIW read the following link.
It is quite peculiar that many will bathe so often as to require constant use of moisturizers and conditioners to return what they regularly strip off. Moderation in all things. Every day is fine. Every other day can be fine. Sometimes just a quick cool rinse is fine. Give your skin a break...
I just don't want to be the smelly kid!
Honestly, the shower before class is what I jokingly call the courtesy shower, and just a rinse after class doesn't make me feel clean enough to go to bed afterwards.
